So I love my SCAR17. Been eyeing a 16 for a long time. The 556 round doesnt do a lot for me other than it used to let me shoot cheap. I currently hunt by day with my 17 and hunt by night with a Noveske 6.8 AR. Would like to ditch the AR and have a SCAR16 in 6.8 as my night gun. Anyone use the HHD conversion or have some other way you can recommend to shoot the SCAR in 6.8?
